Business Intelligence Capabilities and Firm Performance: A Study in China     

《International Journal of Information Management》2021

The development of artificial intelligence (AI) technology expands the boundary of business practice, inducing the emergence and application of business intelligence (BI) that has promoted the transformation of information techniques to optimize business decision and operation. However, there is a lack of theoretical consensus and measurement of the technology embedded in BI at present. This study exploratively develops the Sense-Transform-Drive (STD) conceptual model of BI based on dynamic capabilities theory and organizational evolutionary theory to explain the core BI capabilities. By using factoring analysis and structural equation modeling analysis, we extract the latent constructs and empirically verify the validity of the STD model and further examine the correlation and mode of interaction of the three core BI capabilities and the impact of BI application on firm performance in the real economy with a sample contextual to Chinese business practices. The study results show that there are direct and high-intensity cumulative positive effects among the structural components of the STD conceptual model and BI-related dynamic capabilities can enhance operating efficiency and firm performance.  相似文献

戴志翔  胡诗玮  罗坤  高翔  樊建人  岑可法 《中国科学院大学学报》2017,34(2):179-185

基于CMAQ模拟结果，统计、归纳出各种污染物排放控制因子与污染物浓度之间的函数关系，建立空气质量响应曲面模型RSM，通过留一法交叉验证和外部验证对模型进行可靠性验证。使用RSM，研究不同污染物的PM_2.5响应值，评估现有政策不变（Ⅰ）和政策收紧（Ⅱ）两种减排情景，发现NO_X、SO₂、NH₃和VOC对PM_2.5浓度体现明显的非线性响应特征，情景Ⅱ的减排效果明显好于情景Ⅰ，夏季的减排效果好于冬季。  相似文献   

HAPA理论背景下大学生锻炼行为与锻炼效果的干预研究          下载免费PDF全文

王银晖 《河北体育学院学报》2016,30(4):53-60

以健康行动过程取向理论为理论背景,对644名在校大学生进行教育干预实验研究.干预措施包括课堂和课下指导、微信等即时通信工具宣传、发放健康行为宣传册等,干预时间为10周.在干预前后共进行了两次问卷调查、三次身体素质测试.结果:①根据HAPA阶段划分,大学生大部分处于健康锻炼行为无意向和意向阶段,仅有14.1％处于行动阶段;②干预对大学生锻炼行为意向水平和体育锻炼等级具有积极影响;③干预对大学生身体素质整体水平有积极影响;④锻炼自我效能作为社会认知变量在健康行为过程取向理论的各个阶段都发挥重要作用.建议通过提高个体锻炼自我效能感和制订合适的锻炼计划增加大学生中参加有规律的体育锻炼人数比例.  相似文献

Thomas Tryon,Sheep and the Politics of Eden     

Geoffrey Plank 《Cultural and Social History》2017,14(5):565-581

The English writer Thomas Tryon (1634–1703) believed that sheep were survivors from the original earthly paradise, and that as morally perfect beings they could serve as role models for humans. Tryon advocated vegetarianism, pacifism and an end to slavery as it was practiced in the Caribbean. He was an ambitious and influential reformer on several fronts, but the restoration of Eden was his ultimate goal. Tryon celebrated sheep-like meekness, a stance that complicated his reform efforts. His agenda and sheep-inspired persuasive strategy reflect the momentous intellectual and moral ferment surrounding human relations with animals in the seventeenth century.  相似文献   

Psychological complaints reported by sexually abused children during criminal investigations: Istanbul example     

《Child abuse & neglect》2016

The present study aims at describing the psychological complaints reported, as a part of the criminal investigation process, by the victims of sexual abuse as a part of the criminal investigation process, without attempting at reaching a medical diagnosis; and it discusses the relation of these reports with variables such as victim's gender, age and relation to the offender, type and duration of abuse, and parental marital status of the victim. Data is obtained from the statements of childhood sexual abuse (CSA) victims under the age of 15, as taken by Istanbul Juvenile Justice Department between the years 2009 and 2012. The sample consists of 175 cases with a total of 202 victim statements. Through the use of content analysis, the main and sub-categories of themes of the statements were determined. By means of the evaluation of the psychological condition of victims, we evaluated them in two categories: psychological complaints including self-harm and risk taking behaviors and psychological complaints with no self-harm and risk taking behaviors. The statistical analyses yield significant relations between the psychological complaints and children's parental marital status. Analysis of initial statements of sexual abuse victims is important as it may greatly contribute to professionals diagnosing and treating psychological complaints of these victims. It is essential that victims of sexual abuse should receive immediate psychological support starting with the criminal investigation process.  相似文献   

Piece-by-Piece Review of Digitize-and-Lend Projects through the Lens of Copyright and Fair Use     

Michelle M. Wu 《Legal Reference Services Quarterly》2017,36(2):51-73

Digitize-and-lend library projects can benefit societies in multiple ways, from providing information to people in remote areas or with physical disabilities to facilitating the sharing of library resources with information-poor communities. This article explores the potential of digitize and lend as well as outlines how projects can be undertaken in a manner respectful of the balance of copyright.  相似文献   

Heritage education in the Primary School Standard Curriculum of Malaysia     

《Teaching and Teacher Education》2017

Due to the importance of education for sustainable heritage preservation, it is imperative to pay attention to how heritage is taught in the education system. As a multicultural country with a rich cultural heritage, Malaysia is home to four world heritage sites. This paper investigates Malaysia's new primary school curriculum to determine to what extent the core curriculum cultivates an awareness of and sense of respect for heritage. The results reveal a focus on Malaysian intangible cultural heritage in some core subjects, such as history, Bahasa Malaysia, art, and music education.  相似文献   

基于相对全变分的复杂背景SAR图像舰船尾迹检测     

杨国铮  禹晶  孙卫东 《中国科学院大学学报》2017,34(6):734-742

SAR图像舰船尾迹检测不仅能够反演运动舰船的航速航向信息，也有助于发现图像中弱小的舰船目标。现有的舰船尾迹检测方法对于简单背景SAR图像的检测效果较好，但复杂背景下的检测效果难以满足使用要求。提出一种基于能量泛函极小化的复杂背景SAR图像舰船尾迹检测方法。该方法采用相对全变分技术将图像分解为包含舰船尾迹的光滑成分和海背景纹理成分，通过剪切波变换高频系数重构增强光滑成分，再通过Radon变换检测光滑成分中的尾迹线。比对实验结果表明，本文所提方法对于复杂背景SAR图像的舰船尾迹检测效果明显优于现有的方法。  相似文献
